Code: 06-PP4

U.O.M. - Each

RAM Petrolatum Primer, 4kg - the 1st step in the petrolatum pipe protection process, fills surface imperfections and ensures intimate contact between mastic tapes and is used to prepare, seal and waterproof metal surfaces whilst protecting pipelines from corrosion above and below ground. Ideal for use as a rust preventative on exposed metalwork. Petrolatum tape is similar to Denso tape.

Surface Preparation

Wire brush dirt, loose rust and foreign matter from surface to be protected.Surfaces should be reasonably dry. On wet surfaces use RAM Marine Primer.

Priming

Apply a thin even film of RAM Primer over the metal surface by gloved hand.

Filling

RAM Moulding Mastic should be used where necessary to improve contours at fittings to achieve a streamline contour. The wrapped fitting with the specified overlap must have no voids, air bubbles and wrinkles.

Taping

Start applying the RAM Petrolatum Tape with a full circumferential turn around the fitting and utilize a nominal 50% overlap to achieve a double thickness of tape. Apply tape ensuring firm tension and then smooth down by hand to exclude any moisture and/or water. On each new roll of tape, underlap the new roll on previous by a minimum 100 mm.

Overwrapping

RAM High Temperature Outer Wrap should be spirally wrapped (similar to previous procedure) under tension to guarantee contact to achieve a nominal 50% overlap.
